Bad motherboard?

Well after many hours of testing & playing.
I have found that if i enable DMA on any ATA66 drive that is on IDE channle 1 the peformace while doing the file transfers from disc/cdrom other hard drive, whatever brings the system to a near stop for a several seconds depending on how large the file was that i transfered. (moving a 4MB MP3 will make the system pause for around 15-20 seconds)

However the exact same ATA66 devices can have DMA enabled on IDE channle 2 without any probles.

Strange eh.
I am thinking the motherboard IDE controller maybe messed up or something.
The only cards in my computer are the video & network card.
the motherboard is a Abit KT7 (non-raid)
running a TB 800 @ 800
256MB of PC133 (2 sticks) they have been moved around & it didnt help any.

does anyone know of anyway i can findout for sure its the motherboard? i cant really think of it being anything else? RAM? PowerSupply????
I am just afraid to RMA it back & have them tell me nothing is wrong with the board, since for the most part it is working fine.

PS. i have the newest BIOS update, have tried this on fresh installs of Windows with & without the via 4in1s.
 
Give us a list of exactly what is on each channel (Primary Master,Slave ect.)
Are you using a new ATA66 cable with the blue end going to the M.B./black end for master and Gray for slave?
Everything properly recognized in the bios?
